4 Hardware Setup

The hardware required to run the motor control is the LAUNCHXL-F280049C LaunchPad development kit, the DRV8328AEVM, a Micro-USB cable, and a power supply with a DC output from 4.5-V to 60-V. Follow these steps to set up the evaluation module:

  1. Ensure all resistors, jumpers, and switches are set up accordingly according to the device variant used. The DRV8328AEVM by default is populated with and configured for the DRV8328A. If using the DRV8328C or DRV8328D, please follow Section 3.4.2 to configure the board for the DRV8328x device variant populated for U1.

  2. Mate the DRV8328AEVM board to the top half of the LAUNCHXL-F280049C LaunchPad development kit (mates to J1/J3 and J2/J4 of LaunchPad, as in Figure 3-3). Observe the correct orientation when placing DRV8328AEVM to the LAUNCHXL-F280049C. The motor and power connectors should face to the LaunchPad’s Micro-USB connector.

  3. Connect the three phases from the brushless-DC motor to the 3-pin connector J12 on DRV8328AEVM. Phases OUTA, OUTB, and OUTC are labeled in white silkscreen on the PCB top layer. If using a sensored algorithm on the LaunchPad development kit, connect Hall sensors to the 5-pin connector J10.

  4. Connect the DC power supply to header J9. Observe the correct polarity PVDD and GND connections on the DRV8328AEVM connector J9.

  5. Connect a Micro-USB cable to the LaunchPad development kit and computer.

  6. Turn on the power supply and power up the PCB.

If using the DRV8328AEVM with an external microcontroller, make the connections needed on the male headers on the top of the board or female connectors on the bottom side of the board.
